Subject: [PATCH] [YouTube] Add a StreamExtractor test for a video without
 visual metadata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The video "Makani’s first commercial-scale energy kite" (video ID:
An8vtD1FDqs), which has this behavior, is used for the new test,
NoVisualMetadataVideoTest, added in YoutubeStreamExtractorDefaultTest.

Tests of elements who throw an exception in this case (subscriber count, like
count, uploader avatar URL) test if the ParsingException exception is thrown by
YoutubeStreamExtractor.
